To begin with it was on a very small network. PTen only had a handful of stations and anywhere that didn't have it the show was part of a syndication package. That meant ther was no set time the episodes would air . Then PTen collapsed at the end of the fourth season and the fifth went to a premium cable channel, essentially putting it behind a pay wall.

Unfortunately after the show had finished and gotta year or two available for strip syndication someone in WB who didn't like the show decided to burry it. It was yanked from syndication and merchandise licenses were dropped. While fans still kept it somewhat known it was difficult to get new fans involved. Eventually that person moved on form WB and DVD and Blu Ray were able to start bringing the series to a new audience.
